Some PCs have one, others have multiple. Their main component is called an arithmetic logic unit (ALU.) These do all the work in a PC as arithmetic problems. Processors are mainly made by Intel and AMD.

The Motherboard

The motherboard is the main component of any PC. They connect everything together, and have chipsets in place to aid the CPU. The CPU is seated on the motherboard and receives data from the many components connected to it. The board itself is made of silicon with many tiny wires running along it.

Random Access Memory

Random Access Memory is another component on the motherboard. RAM, as it is usually abbreviated, stores instructions for the processor. If you have a document on screen, but you've not saved it

Hard Drive Disk

The hard drive is another type of memory. However, a hard drive does retain it's information even after the PC has been turned off. Most hard drives contain powerful magnets, metal disks called platters, and a very small needle to write information on these platters.

Power Supply
